Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3750, here are decompositions:

11 + 3739 = 3750
17 + 3733 = 3750
23 + 3727 = 3750
31 + 3719 = 3750
41 + 3709 = 3750
53 + 3697 = 3750
59 + 3691 = 3750
73 + 3677 = 3750

Showing the first eight; more decompositions exist.
